SPECIFICATIQN forming part of Letters Patent No. 67, 7, dated ry 1- Application filed February 8, 1900. b'erial No. 4,542. (No model.)

To all whom it may concern:

Beit known that I, HUGH MCKEE, of Derby, in the county of New Haven and State of Connecticut, have invented a new Improvement in Looms; and I do hereby declare the following, When taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, aside view of the front part of a loom with my improved attachment applied thereto; Fig. 2, a broken top or plan View of the same; Fig. 3, a broken front view; Fig. 4, a broken front view of my improved latch enlarged; Fig. 5, an end view of the same.

This invention relates to an improvement in looms, and particularly to the means for automatically stopping and holding the takeup when the filling runs out or is broken.

Various means have been arranged for-automatically stopping the loom when the filling-thread breaks, but usually the take-up is not locked out, so thatit continues to take up after the filling breaks, and this causes a space between the filling-threads in the fabric no less the weave is worked back, and in working back it is frequently worked back beyond the position where the break took place, and hence a thick place is formed. This is especially the case in weaving coarse mesh-as, for instance, material for ham mocks.

The object of this invention is to provide an automatic device to throw the take-up out when the filling has run out or breaks, and to lock the take-up motion out until the filling-thread is again in order and the loom started, and so as to make it unnecessary to take back in again starting the loom and avoid the formation of thin or thick places in the goods; and it consists in the construct-ion as hereinafter described,and particularly recited in the claim.

In illustrating my invention I have shown a loom of ordinary construction and com prising a filling-slide A, mounted in the top of the frame B and carrying at its inner end a fork C, which is pivotally mounted in the slide, and formed at its outer end with a hook C, adapted to engage with the upper end of one arm D of a bell-crank lever, the other arm D of which is raised every time the lay-sword E comes up. The lay-sword E is connected with a short rock-shaft F by links EE and on the rock-shaft is a U-shaped lever F to which a take-up arm F is connected eccentrically with the rock-shaft, and the free end of the arm F engages with the teeth of a take up ratchet-wheel G, which is mounted on a shaft G,, on theinner end of which is a gearwheel G meshing with a gear H on the takeup roll H, and so that as the lay-sword comes up it forces the take-up arm forward so as to engage with another tooth in the take-up ratchet wheel G, and then when the laysword goes back the take-up arm will move the ratchet so as to turn the take-up roll to the desired extent; A pawl Iis arranged to hold the ratchet-wheel G against reverse movement when the take-up arm is being moved forward. To hold the pawl in position, Iattach to it a weight I. At one side of the machine a belt-shipping lever J is arranged, the said lever extending. upward through a slot J in a top plate J and at the inner end of the slot is a locking-notch J To the front B of the frame I secure a plate L, on which is mounted a rock-shaft M, and on one end of the rock-shaft is a finger N, which extends upward into a position in line with the filling-slide A. The outer end of the rock-shaft M projects beyond the side of the loom and carries two inwardly-extending arms Q and R. The arm Q is connected with the take-up arm F by a chain Q, and the arm R is connected with the pawl I by a chain R, and so that when the arms Q R are raised the take-up arm and pawl will be lifted out of engagement with the take-up ratchet-wheel G,and thereby stop the movement of the takeup roll H. In order that the take-up roll will start from the point where it stood when the filling-thread breaks or runs out, I connect a drag-latch S with an arm S, mounted on the same shaft as the pawl I, and so that the outer end of the latch will engage with the teeth of the ratchet-wheel G when the pawl I is lifted out of engagement therewith, which allows the ratchet-wheel to go back as many teeth as necessary in order to prevent thin places in the cloth due to overmotion when the filling breaks or runs out. When the pawl and take-up are lifted out, the drag-latch straightens out and lets the wheel back, thereby compensating for overmotion of the loom, and avoids the necessity of manually letting back the ratchet, and thus makes the loom automatic and prevents the formation of thin places.

As thus far described the mechanism is that of a well-known loom, and the operation is as follows: As the lay comes up the thread T, held by the grate U, will strike the fork O and lift the nose 0 out of engagement with the arm D and allow that arm to swing without moving the filling-slide, and this move ment of the fork is repeated at every movement of the lay until the filling-thread T runs out or breaks. Then as the lay moves up, there being no thread to lift the fork O and throw the nose 0 out of the path of the lever D, the lever engaging with that nose will move the filling-slide, and this movement of the filling-slide through the finger N turns the rock-shaft M and lifts the levers Q R, and thus stops the take-up. The same movement of the filling-slide strikes a lever V, which is pivoted to the guide-plate J and so as to throw the belt-shipping lever out of the notch J and allow it under the action of a spring W to move to the other end of the slot J, and thus throw the belts 0E and stop the loom; but if the finger-N is not held back when moved by the slide it follows that the continued movement of the loom will allow the levers to continue to drop and the take up arms and ratchet to engage with the takeup ratchet-wheel. To avoid this continued movement, I provide a latch O, which is pivoted to the plate L independent of the fillingslide and formed with a nose 0, which is adapted to pass beneath the inner face of the fingerN when it is thrown outward, as clearly shown in Figs. 4 and 5, and on this latch is a lug O to which a spring 0 is attached, the tendency of which is to draw the nose of the latch toward the finger N. Fixed to the horizontal bar K is an upwardly-extending arm P, which projects into line with the lug O and so that when the belt-shipping lever is moved to throw the belt on the arm P will strike the lug O and throw the nose of the latch out of engagement with the fingerN and allow that finger to turn forward against the end of the filling-slide and so as to be in position to be turned thereby the next time the filling-slide moves forward. It is thus apparent that when the finger is held by the latch the lay may come up any number of times without the filling-thread and not move the take-up.

By arranging the horizontal rod K in connection with the belt-shipping lever the loom may be started in any position where it is possible to grasp this rod, as the movement of the rod not only moves the beltshipper, but operates the latch, so that when the loom starts the latch will be thrown out of engagement with the finger.

It is evident without further illustration or description that the locking-latch may be otherwise arranged and released. I therefore do not wish to be understood as limiting the invention to the exact construction shown.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a loom, the combination with the fillingslide, a finger mounted on a rock-shaft adapted to be moved thereby, and means connected with said shaft to throw the take-up out of action, of a spring-latch pivotally mounted on the frame adjacent to said finger but independent of the filling-slide, and adapted to be passed in rear of the finger when the finger moves outward, a belt-shipping lever, a horizontal rod connected therewith and extending across the front of the loom, and an arm secured to the said rod and adapted to throw the said latch out of engagement with the finger when the belt-shipping lever is thrown on, and whereby the loom may be started from any point within reach of said rod, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

HUGH MCKEE.
